Back home from Norway

Ferry from Lofoten

As I wrote in my previous post we took the ferry from Moskenes to Bodø at 07:00 on Friday.

We left the cabin at 04:30 to make sure we got there on time. It was just 89km, but Google Maps told me it would take me 1 hour and 30 minutes. Due to the snow, wind and darkness it took us 1:48 to get there. In time for the ferry!

After 3 hours and 15 minutes we arrived in Bodø to head towards the SuperCharger in Grong. A 512km drive.

To Grong

The trip to Grong was long. Nothing really special to mention. Ice and snow on the roads, that is mainly it. A exhausting and long drive mainly.

Fiskevägen all over again!

We took the Fiskevägen route. This time from Grong to Krokom where I took it the other way around last year.

The 240km trip took us 4 hours and 30 minutes. We took it slowly since the view is just awesome!

Halfway we stopped in Rötviken to take a break and charge. Just as last year it was just a 3,6kW charger. It added only 4km of range while we took a break. We did it mainly for the show.

Free 50kW CHAdeMO charger

Getting from the Krokom (Sweden) SuperCharger to the one in Mora (Sweden) is over 300km and I don’t like such long stretches. At home I already found a free CHAdeMO charger in Sveg which is a small town along the E45 from Krokom to Mora.

I should be just a matter of plug in and hit the start button. It was!

This charger is also part of the Green Highway. Much better than the 3,6kW charger in Rötviken!

We stayed in a Hotel in Sveg. So during our dinner in Sveg the car could fully charge.

‘Almost’ Home

From Sveg we followed the E45 towards Göteborg and down to Malmö and into Denmark. Slept in Bremen and drove the last 600km home.

This part of the trip was not that special. We just drove for 2 days 🙂

Energy Consumption

When I left home I hit the reset button for both trip counters. The end result is 5.571,3km with a total energy consumption of 1,179kWh. That averages to 212Wh/km.

From Middelburg to Trondheim

To Hirtshals

Last Saturday we left at 08:00 from Middelburg for the 1.100km drive to Hirtshals, Denmark. From there we would take the ferry to Larvik, Norway on Sunday morning.

It took us 14 hours to reach Hirtshals. Traffic was bad, very bad starting at Hamburg towards the border. Roadworks and border controls made it stop and go over almost 100km!

A short night followed since our ferry left at 08:00.

Lier South SuperCharger

After arriving in Larvik our first SuperCharger in Norway was Lier South, 100km from Larvik.

It was busy! After we parked all 8 stalls are occupied. Other Model S had to wait in the queue.

A queue is bad, but it also shows that the infrastructure is used! It’s not a charger which is rarely used. From what I understood it was also a vacation period, so that might have caused the spike in traffic.

Lillehammer

After charging in Lier we headed to Lillehammer. We would stay the night there and charge again.

Fortum CHAdeMO

While heading to Lillehammer I stopped at a CHAdeMO from Fortum to see if I could charge there. The people from Fortum told me that I could use my Dutch phone and send a SMS to active it.

Well, that didn’t work. I borrowed a RFID tag from somebody else as a backup. On the Lofoten Islands I will need to use a Fortum charger, so I wanted to know if it worked. Lesson learned. It doesn’t.

Busy times at Lillehammer

On the E6 to Lillehammer we already spotted a lot of Model S coming from Lillehammer, so I expected the SuperCharger to be crowded.

It was! 9 of the 10 stalls we busy, so we parked at the last stall available.

As we were charging we saw more Model S arrive. We still had 100km left in the battery and we would leave the next morning. We vacated the stall and to decided to charge the next morning for the 155km drive to Dombas and Trondheim.

We checked in at the hotel and went for a dinner in Lillehammer.

SuperCharging with a cold battery

The next morning the car had been in -8C for the night. When I switched to ‘Drive’ a warning indicated that regenerative braking had been disabled. This was due to the battery being cold.

SuperCharging didn’t go very fast. When I just started it would charge with 17kW and slowly climbed to roughly 30kW before we had enough to leave for Dombas.

This was a similar experience as last year at the Krokom SuperCharger in -22C.

The picture below shows that we were charging with 24kW where under normal conditions it should have been about 80kW.

To Trondheim

From Lillehammer we drove to the Dombas SuperCharger. After a charge and lunch there we headed down to Klett (near Trondheim).

Nothing really special on this part of the trip. The temperature was about -5C and the (road) conditions were good.

To the Lofoten

Our destination is a house we rented through Airbnb on the Lofoten Islands.

From Trondheim we are taking the Hurtigruten ferry to Stamsund on the Lofoten. This will take 2 days.

From Stamsund to the house it is just 21km. Time to relax!

Energy Consumption

The tripmeter shows 1861km and a total usage of 391kWh. That’s 210Wh/km. Not bad at all!

Fully electric to Norway, again!

Last Year

In the beginning of 2015 I drove a 5.500km trip with my father to the most Northern Tesla Motors SuperCharger. For a few reasons:

To see the Aurora Borealis
To prove it can be done with an electric car
Because I like roadtrips and travelling

This winter I’m going it again!

My Model S

I have a ‘classic’ Model S from September 2013. No Auto-Pilot features or All-Wheel drive. It’s a 85kWh RWD model.

The ODO currently displays 110.000km and when we get back it won’t be long before I hit the 120.000km.

Still enjoying this car every time I drive it.

Lofoten

My girlfriend also wants to go to Norway to see the Aurora Borealis. She heard me telling her all the stories for over a year about how great it was and how much I like Norway.

So I said: “Why don’t we go there?”

This year the destination will be the Lofoten Islands. From what I’ve seen and heard it is about the best place to watch the Aurora Borealis!

Route to Lofoten

Our route will take us from Middelburg (Netherlands) to Hirtshals (Denmark) where we take the ferry towards Larvik (Norway). Following the Tesla SuperChargers we will drive to Bodø from where we take the ferry to the Lofoten Islands.

On the Lofoten there are no Tesla SuperChargers, so I’ll be using the CHAdeMO chargers using the CHAdeMO adapter to charge my Model S there.

I found these CHAdeMO chargers on elbil.no’s Hurtigladekartet and on uppladdning.nu.

Route back home

We’ll drive back through Sweden where I want to take Fiskevägen again. What a beautiful route!

The total route should be about 6.000km

Preparations

Since I did almost all the preparing last year already I still have about everything I need.

Making sure we have enough water, food, heat and proper winter gear with us. We should be fine!

3-phase and CHAdeMO charging for the Model S?

The biggest issue with Electric Vehicles (EV’s) is charging. How do I charge my car within a reasonable time frame? Charging within 1 hour is possible, but you need a lot of power to do so. That is not available on all locations and requires special chargers.

Almost two years ago I made a reservation for a Tesla Model S, the car which I think is the best EV to come to the market.

In the summer of 2011 I was invited to a ‘reservation holder only event‘ at the Tesla factory in Fremont California. I went there and saw the Model S for the first time: Wow…. I was blown away, what a beauty.

EV’s however are new and not everything is technically the way you want it to be.

What is 3-phase charging and why would you want it?

Timely charging is the biggest issue with EV’s. With 3-phase charging you could charge your EV 3 times faster, since Europe has a 3-phase power grid.

I live in Europe (The Netherlands) and unlike the USA were are limited to ~32A per phase. In the USA you can get a 100 Amp installation in your house. Amps and Volts is all that counts when you want to charge an EV.

With a 100 Amp connection in the USA, you get 20kW of power. (100A * 208V =~ 20kW). The biggest battery of a Model S is 85kWh (Kilowatt hour). 85 kWh / 20kW = 4.25 hour of charging (not taking any losses into account).

Like mentioned, in Europe we have a 3-phase power grid and we are limited to 32A per phase in residential areas (Rules are complex!). 32A at 230V = 7.3kW.

The 85kWh battery of a Model S would take almost 12 hours (85 / 7.3) to charge.

Here comes the 3-phase power into play. We can get 3 times 32A in our hose at 400 Volts. (See the Wikipedia page). This calculation is a bit more complex: 400 * 32 * SQ(3) =~ 20kW. We also get 20kW of power in our residential areas, but it’s delivered to us spread out over 3-phases instead of one.

The bottom-line is: Without 3-phase charging it will take three times longer to charge a Model S in Europe then in the USA. That’s why I want 3-phase charging for the Model S.

When I made my reservation the Tesla website stated that the Model S could charge from 110V, 220V and 480V. From that moment I assumed the Model S would support 3-phase charging, but then I went to the event at the factory in Fremont.

This picture shows the new charging connector of the Model S. Tesla designed a new connector which could handle AC (low to medium (20kW)) power and DC (high >50kW)) power over the same pin layout. This results in a very sleek connector. A great connector if you look at it from a designers perspective.

The connector is however lacking a 2nd and 3rd connector for 3-phase charging. This connector design only has:

A ground (bottom middle)
A proximity and pilot connection (bottom left and right)
A Phase connection (top left or right)
A neutral connection (top left or right)

In order to support 3-phase power the connector should have two more ‘big’ connectors.

I asked a Tesla employee if the Model S could charge from 3-phases and he said “No, it won’t” I felt really disappointed. I had been waiting on the Model S for such a long time already (18 months), living with the assumption (since the website stated 480V charging) that it would support 3-phase charging.

The employee told me that Tesla focused on Quick/Fast/Super-charging a Model S with high power DC (500V, ~200A, 90kW, 45 min) instead of the slower charging. The Model S would also be able to travel such long distances that you could do almost all your driving without charging. I argued he was wrong, but it was quite busy at the event, so I didn’t get into a in-depth discussion with him.

Although the event at the Tesla factory was great, the news about the lack of 3-phase charging gave a real bad taste.

In the car back to the hotel I started brainstorming with my colleague (the Roadster owner) about how we could convince Tesla otherwise. As a Roadster owner in Europe he’s also quite disappointed about the Roadsters limitation to 7kW (32A @ 230V) charging (8 hours) in Europe. He however accepted it since the Roadster is a car for pioneers, early adopters or tech freaks, however you want to call them.

If you by a base Model S you get one on-board 10kW AC charger, but if you pay $1500,00 you get a second 10kW charger which runs parallel with the first charger, giving you 20kW AC charging.

Wait a minute? 20kW AC charging? That is exactly what we want in Europe! In the US the chargers run parallel on 1-phase, as Europeans we want the 20kW spread out over 3-phases. So what is the point? Tesla clearly sees that 20kW AC charging is useful in the US, why not in Europe?

To get back to the brainstorming: We came up with the idea to write a letter to Tesla and start collection signatures from people who agreed with me. So I did, I wrote a letter to Tesla together with 39 hand written signatures.

On the right two pictures of how this looked.

On November 4th 2011 I sent this package to the Tesla HQ in Palo Alto, CA, USA and I started waiting…

After a month of waiting for just a “Thank you for your letter” I also sent the letter to the Tesla EU HQ in London and posted a Tweet. That is when I got a “Thank you” from Tesla, but nothing conclusive. I never expected Tesla to reply within a month with a answer that they would or wouldn’t support 3-phase charging.

I completely understand that such decisions might have a big impact and involve a lot of people, so these kind of things take time.

However, is implementing 3-phase support that hard? I think it’s not. The biggest obstacle I think is the connector (see above) that Tesla designed. It’s missing the necessary connections for L2 (2nd phase) and L3 (3rd phase), so they would have to redesign that connector. They could also add a second charging port on the car and support the IEC 62192-2-2 connector natively without any adapters?

3-phase charging would drastically improve the usage of the Model S. On a 3x16A (10kW) connection you could charge a Model S with it’s 85kWh battery in about 8 hours. A Nissan Leaf also charges in 8 hours, but a full charge of a Leaf gets you 160km, a full Model S takes you up to 480km.

A 3x32A connection (20kW) could charge a Model S in a bit over 4 hours.

I made a graph to display the various charging times for a Model S and a Roadster. You get the picture why 3-phase charging is really needed for the Model S!

Without 3-phase charging you wouldn’t even be able to charge your Model S overnight! How are you supposed to charge the Model S if you get back home later in the evening and want to leave the next morning? A full charge could take over 24 hours!

Most (bigger) hotels in Europe also have a 3-phase connection available somewhere in the parking lot, if not, it is trivial to get such a connection installed. With just a single-phase socket you can’t charge your Model S overnight (see the chart above).

That is why I emphasized this to Tesla: “European’s don’t want 3-phase charging, they need 3-phase charging!”

The faster you can charge your EV, the better. It makes the car more practical, simple as that.

The final decision is at Tesla, but I think that supporting 3-phase charging is trivial and vital for Tesla if they want to be successful in Europe. In my letter to Tesla I showed them how many 3-phase charging stations are available in Europe. The current estimate is that over 2.500 (~1300 in Holland alone!) of these charging stations are installed in Northern Europe and they are being installed on a daily basis. (Amsterdam is installing at least one every week).

We just saw the release of the Pricing & Options of the US Model S, so I’m not expecting a answer from Tesla really soon. I however have good hope that Tesla will implement 3-phase charging for the Model S. My hope is that they will reveal it at the Geneva Motor Show in March 2012.

Something else which has been bothering me is the DC (fast-charging) charging Tesla will be using for the Model S. They say it will be DC charging at 500V and can top up your Model S in 45 minutes. They call it “Supercharging”.

Around the world (especially in Europe and Japan) fast-chargers are being installed which are compliant to the CHAdeMO protocol.

CHAdeMO is a fast-charge protocol which delivers up to 50kW of power. If we take a look again at the calculations above: 85kWh / 50kW = 1.7 hours for a full charge.

The Nissan Leaf is one of the first cars to support CHAdeMO fast-charging. A CHAdeMO station can recharge the 24kWh battery of a Leaf in 30 minutes.

Yes, the 50kW a CHAdeMO charger delivers is 60% of the 90kW Tesla is intending to use, but still, 50kW is better then nothing.

Tesla claims that they will be installing their “Super chargers” throughout the US and even Europe, concrete plans are however lacking.

The CHAdeMO chargers are being rolled out today. Nissan recently said that they will donate 400 chargers in Europe. 400 chargers!? That is great! If the Model S could take advantage of these chargers you could travel even further.

CHAdeMO seems to be winning in Europe and Japan as it comes to fast-charging. I’m not sure about the US, but it seems it’s getting traction there as well. In 2012 there will be hundreds or more then a thousand of these chargers throughout Europe. It would be a shame if the Model S can’t charge there.

BP (British Petroleum) has started installing CHAdeMO chargers at their stations along highways in the Netherlands, but incentives like those are being initiated all over Europe. In 2011 the Norwegian energy company Ishasvkraft announced that they will be installing CHAdeMO chargers throughout Norway. Lysi Energy is doing the same in Norway.

On the Tesla Motors Club forum I recently started a thread on CHAdeMO charging for the Model S. We can be almost a 100% sure that the Model S won’t natively support CHAdeMO charging, but there is always the possibility of an adapter. Tesla did not reveal any plans for such an adapter, but there is hope.

My message to Tesla is that they should make the Model S the best EV on the planet and crush all competition. I’m blown away by the Model S and can’t wait to receive mine. It would however be a shame if the car would be limiting me by not letting me take advantage of the available power provided by 3-phase and CHAdeMO charging stations.

The specifications of the Model S are great, no doubt about that. Just make sure that I as a driver can take full advantage of all the charging possibilities which are available. That would make me (and I think a lot with me) a very, very, very happy customer!
